Celtic Mythology is the mythology of the Celts, a group of tribal societies present across Europe during the Iron Age and in Medieval times.
In Toaru Majutsu no Index, Celtic Mythology is used as a base for certain forms of Magic.
There are two main (surviving) strands of Celtic mythology: Goidelic (Irish/Scots/Manx) and Brythonic (Welsh/Cornish/Breton). While they share many traits and have certain figures in common, they do not really overlap; each has its own unique stories. They are further split into 'Cycles' (Ireland) and 'Branches' (Wales). Mainland Europe's Celtic traditions were mostly lost due to invasion and assimilation of Celtic populations in their conquerors' own societies (mainly The Roman Empire and Germanic tribes). The cultural taboo against consigning knowledge to writing certainly didn't help.
Uses of Celtic Mythology in the story
- Fragarach: The sword of Manannan mac Lir and Lugh. When held at one's throat, the sword was said to prevent them from telling a lie, hence its name, meaning 'Answerer'.
